form format 10+00

user input into field 10000

Here's a simple general purpose script for this

event.value = event.value.replace(/(\d\d)$/,"+$1");

If you want to change the actual value of the field, this script should be placed in the validation or "WillCommit" event script.

If you just want to change how the field is displayed to the user, then it should be placed in the Format Script.
